TypeA is a single pair cable with an overall shield and is made to meet the high demand of automation engineering. Belcom also offers multipair individually screened cables wherein each pair fulfils type A requiremensts acc. to IEC 61158-2.

Profibus originated in the European market and has become a worldwide standard because of its performance attributes. Profibus consists of several variations which are designed for use in special applications. The two Profibus versions most commonly used are Profibus-DP (Distributed Peripherals) and Profibus-PA (Process Automation).

Profibus-PA was developed to connect directly into Profibus-DP and may be used in intrinsically safe applications. DP uses the RS485 physical layer while PA uses the IEC 61158-2 physical layer designed primarily for process applications

Profibus-DP is recognized as a high performance bus network capable of transmitting thousands of I/O point information in less than a few milliseconds. For that reason it has been used extensively for fast response control applications such as turbine servos and variable speed drives.

Profibus-PA was designed as a substitute for HART and 4 to 20mA signal transmission in the process industries. It uses function blocks designed around process industry requirements and uses the IEC 61158-2 physical layer, making it compatible with intrinsic safety circuits.

Profibus-PA links to the control architecture via Profibus-DP with a segment coupler or link as shown. Segment couplers are signal converters that adapt the RS-485 signals to the 61158-2 signal level. They are transparent from the bus protocol point of view. If segment couplers are used, the baud rate on the DP (RS-485) segment must be restricted to 45 Kbits/sec. The segment coupler also injects power into the PA network for the segment instrumentation.

Links are independent devices on the DP network which represent all devices connected to the 61158-2 segment. When PA segments are connected using links there is no limit to the baud rate on the DP segment which enables faster overall bus network performance.

Dekoron Wire & Cable was a leader in the use of Foundation Fieldbus cables for two-way digital communication. Using such cables allows for greater control and monitoring with fewer wires and less installation hassles, even in hazardous locations. Communication is provided over standard twisted-pair wiring and conformance to FF-844 H1 and IEC 61158-2 standards assures a data transmission rate of 31.25 kB/s and superior physical and mechanical performance, even in adverse environments.

Dekoron can offer a variety of ratings and standards for instrumentation products. Please discuss the specific rating and approvals with your customer service representative prior to placing your order. Depending on the cable design and selection of armor types, the following approvals are available:

This standard UNE EN IEC 61158-2:2023 Industrial communication networks - Fieldbus specifications - Part 2: Physical layer specification and service definition (Endorsed by Asociacin Espaola de Normalizacin in May of 2023.) is classified in these ICS categories:

PB FC Process Cable GP/ Ethernet-APL cable GP, bus cable for IEC 61158-2 (PB) and IEC TS 60079-47 (2-WISE) sheath color blue for Ex applications 2-core shielded, sold by the meter delivery unit max. 1000 m minimum order quantity 20 m. Bus cable for use in fieldbus systems according to IEC 61158-2 (e.g. PROFIBUS PA), suitable for non-hazardous applications.Time is saved thanks to easy and quick on-site installation. Reliable shield contact and strain relief as well as efficient EMC shielding. High interference immunity thanks to double shielding. Silicone-free, therefore suitable for use in the automotive industry (for example on paint lines). Easy length measurement thanks to printed meter marking.

IEC 61158-2:2023 is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the 'three-layer' fieldbus reference model described in IEC 61158-1.

This document specifies the electromechanical components for RS 485, Fiber Optic and IEC 61158-2 transmission technology.

This guideline is intended primarily for manufacturers of PROFIBUS field devices and manufacturers of connectors.

The objective of this guideline is to limit the variety of methods utilized in PROFIBUS connections. Connectors for the connection of PROFIBUS field devices are to be preferred to other connection methods because of the advantages for servicing, commissioning and testing.
